What with it being Leveson week the twittersphere has played host to even more spectacular media and  commentariat bitch fights than normal.

MediaGuido gives you the best of the best, kicking off with Fraser Nelson versus Patrick Wintour:

@patrickwintour when I come out of prison, I'd still be able to buy a copy of The Spectator. Guardian would be long gone.

Then ex-Hacked Off campaign co-ordinator Thais Portilho-Shrimpton gave Michael Wolff a schooling:

@MichaelWolffNYC @PeterBale @BrianCathcart Thanks Michael. I don't work for Hacked Off anymore and I'm not a leftie

Rounded off nicely with Alastair Campbell completely losing it with Toby Young:

@toadmeister as dickheads go, you are large

Brian really does bring out the worst in some people…
